he traditional car production workshop can start production as long as the production line is placed in a huge space while separating the employee office, dressing room, material room, product warehouse, etc. With the advancement of science and technology and the popularization of intelligent facilities, in order to meet people's increasing material needs, more and more companies are pursuing to make full use of limited space and rationally plan the layout of production processes. Clean workshops are almost the production workshops of all standard enterprises. Standard. In the design and construction, in addition to the basic smooth drainage inside the conventional workshop, the ground is non-slip, strong and impervious, flat, without water, corrosion-resistant materials, and kept clean, and the workshop outlet and the drainage and ventilation points connected to the outside are installed to prevent rats. , Anti-flies, anti-insect equipment, workshop interior walls, ceilings, doors, windows, waterproof, anti-mold decoration outside the content. Modern production workshops should be finely decorated in accordance with GMP workshop standards. That is to say, during the construction of the workshop, the design and decoration should be carried out according to the "Clean Plant Design Specification" / "Clean Workshop Design Specification" and other relevant specifications. Today, CEIDI Xidi talks about how the GMP clean production workshop should be designed and decorated.

The process layout of GMP clean workshop should meet the following requirements

1. Under the premise of meeting the requirements of the production process, the clean room or clean area with high air cleanliness should be close to the air conditioning room, the processes and studios with the same air cleanliness level should be arranged in a centralized manner, and the air cleanliness level should be arranged near the population of the clean area. Lower studio.

2. The layout is reasonable and compact. Only necessary process equipment and procedures and working rooms with air cleanliness level requirements are arranged in the clean room or clean area.

3. The plant workshop purification project should consider the transportation route for the installation and maintenance of large equipment, and reserve equipment installation ports and inspection ports.

4. The processes that require high air cleanliness in the workshop purification project should be arranged on the windward side, and the process equipment that is prone to pollution should be arranged near the return air outlet.

Tips for decorating GMP clean workshop

I. Layout description of the GMP clean workshop building:

The layout of the building should belong to the scope of the architectural profession, but because many industries, such as the food/beverage industry, aseptic clean workshops require people and objects to be separated, and the static pressure gradient of each clean operation room must be maintained, therefore, the building plan requirements in this project Have the following points:

1. The logistics of the food and beverage aseptic workshop passes through the mechanical interlocking self-sterilizing transfer window from the outer corridor, enters the buffer corridor after disinfection, and then enters the operating rooms through the transfer window.

2. In each purification operation room, an independent front room is set as an air lock, and the air lock room is communicated with each operation room at the same time to ensure that the air in the low-clean area does not penetrate into the high-clean area.

3. The flow of people from the clean room passes through the locker room, changing clothes and shoes → washing room washing hands → buffer room → air shower room → various operating rooms.

II. Material selection for GMP clean workshop

According to the "Code for Design of Clean Workshops", the walls and ceilings of the workshop must be constructed with materials that do not produce dust and do not accumulate dust with a smooth surface, and there must be no dead corners in the workshop. Use special color panels for purification plant construction. The top plate of the base plate is made of Baosteel 0.4 steel plate, the core material density reaches 14kg/m3, and the aluminum material uses purification special aluminum profiles. In order to improve the service life of the purification room and achieve a beautiful and generous effect, all aluminum profiles Perform electrophoresis treatment.

III. Floor of GMP clean workshop

The floor is made of solvent-based epoxy resin, the strength is above C20, and the surface is dense, free of sand, bulging, and cracks. The color is bright, the anti-static performance is constant, can withstand the load below the medium level, and can withstand high temperatures. On the basis of satisfying use, it can play a decorative role, wear-resistant, wash-resistant, dust-proof, non-slip, excellent performance, uniform color and gloss.

IV. Ventilation and air purification equipment in GMP clean workshop

Clean plant design, according to the specification requirements, design the return air system. The computer room is located on the top side of the plant (according to the actual situation, the unit type purification system can be used, and the computer room is not required), and the return air circulation ducts are connected to the air conditioning unit in the technical mezzanine to form a system. The return air duct is made of high-quality galvanized steel plate and is softly connected by a damper. Galvanized steel ducts are made on site. According to the requirements of indoor noise level, the wind speed in the duct should be selected according to the following regulations:

(1) The total air duct is 6 to 10 meters per second.

(2) The branch duct without air supply and return air outlet is 6-8m/s.

(3) The large air duct with air supply and return air outlets is 3 to 6 meters per second.

In summary, how should modern GMP clean workshops be designed and decorated? Or how to design and decorate the best? The specific operations and procedures need to be formulated according to your own needs. CEIDI Xidi designers have rich design experience. Most of them have worked in the 10th Electronic Design Institute and the 11th Electronic Design Institute, and have a 12-year development history of CEIDI West There are quite a lot of benchmark projects in the design and construction of clean workshops. Among them, there is no lack of cooperation with a large number of national key projects and famous enterprises, and they have quite rich experience in design and construction.
